BOLTIGHT have expanded their range of ultrasonic measurement devices with the introduction of Echometer+. The new device uses the latest ultrasonic measurement technology and offers more features and performance than Boltight’s original hand-held Echometer.
Used for monitoring critical bolting applications, either during the installation of new plant or while carrying out routine maintenance, the Echometer+ unit can accurately measure load, stress and elongation on bolts up to 25.40m long.
It works by measuring the time of flight of a sound wave as it travels through a bolt. When the wave hits the end of the bolt it reflects back into the transducer, allowing a measurement to be taken. A new automatic correlation feature on the device is said to ensure accurate and repeatable transducer placement.
As well as being able to measure much longer bolts (25.40m versus 2.44m), Echometer+ is said to offer greater control in terms of how a waveform is transmitted with nine different pulse width options to choose from. Larger in size than the original hand-held Echometer, the new device incorporates additional hardware, including a sunlight-readable colour screen and built-in rechargeable batteries.

TRANSDUCER DATA & SELECTION
There are several things to consider when deciding which transducer to use:
- The crystal diameter should be completely in contact with the bolt end surface.
- The outside diameter should be clear of any obstruction.
- The frequency should be chosen to suit the bolt length.
- The larger the diameter the stronger the signal and therefore better results are obtained by using the largest size transducer that will fit on the bolt.
- Boltight recommends the 3/8” diameter, 5MHz transducer as the best general purpose covering 90% or more of typical bolting applications.
